Old bottles and battery acid can drive production of valuable industrial chemicals

Phys · · 767 words · By Sanjukta Mondal
Waste Reduction Circular Economy Sustainable Chemistry

Researchers at the University of Cambridge have developed a method to produce industrial chemicals called anilines using sunlight, a cobalt molybdenum sulfide catalyst, and hydrogen derived from plastic waste and battery acid. The process aims to provide a more sustainable alternative to traditional manufacturing methods that rely on fossil fuels and high-pressure conditions.
